Abstract: A clutch control device, particularly for automotive vehicles, comprises a manoeuvring member which is coupled axially with a working element which engages the relevant part of the actuating member of the clutch itself. The manoeuvring member and working element are coupled together through a retaining shroud, using an assembly device which comprise a plurality of tabs or lugs projecting from a lateral wall of the retaining shroud and which are able to slide in corresponding axial grooves formed in the manoeuvring member until they leave the grooves on the face of the manoeuvring member opposite to that at which they were introduced. Relative rotation is then carried out between the retaining shroud and the manoeuvring member, so as to engage the tabs securely in radial recesses formed in the radial portion of the manoeuvring member, the recesses being offset by a predetermined angle from the axial grooves.

Abstract: A clutch release bearing comprises a maneuvering member operated on by a control member, usually a clutch release yoke. A drive member in direct or indirect axial bearing engagement with the maneuvering member, when operated on by the latter, operates on the clutch release device of a clutch. An axially acting spring washer of the Belleville spring type urges the drive member against the maneuvering member and retains the drive membering relative to the maneuvering member in the axial direction. This spring washer is able to turn inside out selectively so as to assume one or other of two separate stable configurations. One of these is a concave configuration and the other is a convex configuration. One configuration is an inoperative configuration and the other is an operative one. One peripheral edge of the spring washer bears axially on the drive member when it is in the operative configuration. On its other peripheral edge is a set of lugs through which it bears on the maneuvering member.
